Searching an algorithm.

I am making a program, and I need an algorithm to calculate the watershed basin 
upstream of a outlet point. I know an algorithm that was documented in GRASS 
manuals but doesn't exist, this algorithm was named r.water.outlet.

I would like to have the source code or the A* Search Algorithm to Develop 
Hydrologic Models from Digital Elevation Data (Charles Ehlschlaeger, U.S. Army
Construction Engineering Research Laboratory)

                                       Thanks in advance.
